Question 1 of 5

A nurse is caring for a client who has hypernatremia and requires IV fluid therapy due to his NPO status. Which of the following solutions should the nurse prepare to infuse for this client?

Correct Answer: C

Rationale: The correct answer is C: 0.45% sodium chloride. In hypernatremia, there is an excess of sodium in the body leading to dehydration. 0.45% sodium chloride is a hypotonic solution that will help to dilute the excess sodium in the body and rehydrate the client.

A: Lactated Ringer's is not the best choice as it contains sodium and may worsen hypernatremia.
B: Dextrose $10\%$ in water is a hypertonic solution and may further increase the sodium levels.
D: Dextrose $5\%$ in $0.9\%$ sodium chloride is hypertonic and may not adequately address the dehydration in hypernatremia.

In summary, 0.45% sodium chloride is the most appropriate choice as it helps to correct hypernatremia by providing free water without increasing the sodium levels further.
